It has been reported previously that the parabrachial region supports robust self-stimulation. In the present study, we determined whether lesions of the parabrachial nucleus (PBN) influence the rewarding effect of medial forebrain bundle (MFB) stimulation. In 10 rats, stimulation electrodes were aimed at the lateral hypothalamus and/or ventral tegmental area and a lesioning electrode aimed at the PBN. Rate-frequency curves were collected at each of three stimulation currents at each electrode… CONTINUE READING
